Modern cars, trucks, SUVs, and vans have what seems like millions of sensors that can cause the check engine light on the dash to come on. Some folks drive their vehicles for years and years with the light illuminated. Sometimes, nothing ever comes of the event. That does not mean that something isn’t wrong, though. Other auto owners choose to get their modes of transportation checked out immediately after the check engine light turns on.

Why? Well, for one, if it is something serious, they want the problem fixed as quickly as possible so that they don’t get left stranded on the side of the road. Meanwhile, others take the same action simply because the light is annoying. They hate staring at that bright orange emblem. It can glow so illustrious at times that the light may even impact the driver’s ability to see at night. 

What Can Lead To A Check Engine Light Illuminating?

As mentioned above, lots of things can cause this problem. That is where auto diagnosis comes into play. The technicians at Callahan Automotive in Meza, Arizona have the tools and experience to analyze your particular situation. These things help them determine what part is faulty and what it is doing to the vehicle. Common pieces that make check engine lights shine include but are not limited to…


  • Oxygen Sensors
  • Missing Or Loose Gas Caps
  • Fuel Injectors
  • Misfiring Spark Plugs
  • Catalytic Converters


Not only do these parts make the check engine light turn on, without auto diagnosis, they can cause the engine to idle rough, use excessive amounts of fuel, and lose power. There is no point in taking chances when the treatment could be something simple and cheap. Then again, it is good to know about significant problems early on so that they can be fixed. Consider Callahan Automotive for your auto diagnosis needs, if for nothing else, to give yourself some peace of mind in knowing what is wrong with your car.
